undercoating

[packinheat2]

Im thinking about undercoating the frame rails on my truck. Has anyone else done this?

[jlwelding]

I wonder what Rino liner wound do? I see people camo out there trucks with it, it's got to be some kind of protection.

[packinheat2]

I want to put something down before its too late Im just curious on how it holds. I suppose its all on how you prep it tho.

[jlwelding]

Man I have seen a lot of trucks from up north, they dont look so hot after just a few years.

[packinheat2]

I know the salt does a number on them! Thats why id like to try to protect it with something

[Mopar1973Man]

Yeah I run in the snow and salt up here every year but its hard to tell... :stuned:I wash my frame and underbody about every week or so if the weather is permitting. I make sure to rinse the fender and frame of all the muddy and salt residue.

I knew a guy that claimed that he would spray the underside of his truck so often with WD-40. Im not that decitated

I dont have it on my frame rails but my rockers have been undercoated for over 2 years now, there are a few minor places I need to touch up but other than that it has held up well.-Jordan-

well I bought the undercoating and a gallon of acetone to try to prep everything good. Now I just need to find some free time to do it:lol: I'll let everyone know how it goes.

Well I started my undercoating project yesterday. Everything went good but I didnt get hardly enough Now today it is raining, but what I got done looks good I will have to take some pictures when I get it all done.

The rubberized kind from 3M is the best, but the price is high. It stays nice for a longer time and doesn't peel and get all over your hands of you bump it after a couple of years like the cheapo kind. I get just as good a result from just keeping the frame painted well. If a spot blisters out, I use a rust converter that changes the rust to a black primer, then touch up with more paint and it all looks like new. If you paint, just be sure to use Low Gloss Black, not flat. The semi and gloss black doesn't look OEM.Advance Auto parts sells a real nice Low Gloss Black. It matches the frame sheen perfectly.MoparMan is right. Keep the frame washed everytime you wash the truck. Dirt holds moisture, = RUST.

I didnt get the 3M kind but I have never found anything 3M that doesnt work good

Yes, there has been only a couple of instances where I have been able to bring myself to spend that kind of money for spray can undercoating. I did buy a special gun for spraying undercoating from the body shop supply store about 10 years ago. The undercoating comes in a gallon jug and is more affordable. I came out of that job looking blacker than the President. I have never used it again. I spent hours getting that stuff off of me. The spray cans are by far the easiest and cleanest way. The professional grade undercoating still wasn't as good as 3M. As you stated, it seems that everything that company makes is high quality. The 3M spray seems to cover as much per can as two of the others, so I really don't know if it is that big of a difference in cost in the end.Another thing. NEVER spray undercoating on a windy day. I bought a new truck once and did just that. The paint felt like sand paper, and I had to do a buff job on a truck that I owned for 3 days.I have had a couple of major screw ups with this stuff now that I think of it...Good luck with your project.Bob

I was covered too, luckily because I lay blacktop for a living I have really good hand cleaner that takes everything off just like it were dirt.

[RJC2]

What kind of hand cleaner do you use. I need some. "Ol' blue" has been making me black...

[Mopar1973Man]

How about a few pictures of it???

[packinheat2]

I use Joes hand cleaner, within the last year you can now buy it at O'Reillys but prior to that you had to get it through a dealer, so check out O'Rieillys. And for the pics I will try to remember to take some this weekend when Im putting the new shocks on.

Agreed!

--- Update to the previous post...

I've seen some trucks up here w Rhino Liner on the exterior. It looked pretty good actually. If one was to undercoat & do the bottom of the doors, rockers, that would have to be the best & longest protection.

The real old timers used to spray there vehicles w used motor oil. (UMO) A farmer that I buy hay from has his original equipment from the 50's. he thins his UMO down w D2, just enough so it spays better. He does it every year after hay season is over. I heard storys of guys spraying there cars & driving down dust roads to make the UMO stick better!

[RJC2]

The auction companies (in this area anyway) that auction off used farm equipment do the same UMO and diesel mixed. It makes the dull paint look a little nicer. Just don't sit down on it... Yes I did.
